Beckhoff EL4022 2-Channel Analog Output Terminal

Beckhoff EL4022 EtherCAT Terminal is a two-channel analog output module that provides current outputs in the 4–20 mA range with 12-bit resolution per channel. As part of Beckhoff’s EL40xx family, it integrates into Beckhoff’s EtherCAT I/O system to drive process control devices with precise, real-time control signals. Each channel delivers a controlled current from 4 mA up to 20 mA, suitable for operating loop-powered and other 4–20 mA instrumentation and actuators such as valves, flow meters, or positioners. The 12-bit resolution corresponds to 4096 discrete levels across the 4–20 mA span, enabling fine-grained adjustments and smoother control performance across both outputs. Designed for scalable automation architectures, the EL4022 supports synchronized updating with the rest of an EtherCAT network, ensuring deterministic behavior in multi-channel control loops and compatibility with Beckhoff’s automation ecosystem. Whether expanding an existing EtherCAT I/O node or building a compact 2-channel 4–20 mA output block, the EL4022 provides reliable, high-resolution current outputs within a single terminal housing.
